Summary Introduction
To review:
The consequence of mixing two single stranded DNA molecules isolated from different genes in the presence of highly concentrated salt solution.
Introduction:
A deoxyribonucleic acid (DNA) molecule forms a double helical structure due to the presence of hydrogen bonds between the bases in the two polynucleotide chains. The DNA molecule carries information and stores instructions to make larger
